### Changed

-   Audio analyzer default workers reduced from auto-scale to 2 (memory conservative)
-   Audio analyzer Docker memory limits: 6GB limit, 2GB reservation
-   Download status polling intervals: 5s (active) / 10s (idle) / 30s (none), previously 15s
-   Library pagination options changed to 24/40/80/200 (divisible by 8-column grid)
-   Lidarr download failure detection now has 90-second grace period (3 checks)
-   Lidarr catalog population timeout increased from 45s to 60s
-   Download notifications now use API-driven state instead of local pending state
-   Enrichment stop button now gracefully finishes current item before stopping
-   Per-album enrichment triggers immediately instead of waiting for batch completion
-   Lidarr edition variant detection now proactive (enables `anyReleaseOk` before first search)
-   Discovery system now uses AcquisitionService for unified album/track acquisition
-   Podcast and audiobook time display now shows time remaining instead of total duration
-   Edition variant albums automatically fall back to base title search when edition-specific search fails
-   Stale pending downloads cleaned up after 2 minutes (was indefinite)
-   Download source detection now prioritizes actual service availability over user preference

### Removed

-   Artist delete buttons hidden on mobile to prevent accidental deletion
-   Audio analyzer models volume mount (shadowed built-in models)

### Database Migrations Required

```bash
# Run Prisma migrations
cd backend
npx prisma migrate deploy
```

**New Schema Fields:**

-   `Album.originalYear` - Stores original release year (separate from remaster dates)
-   `SystemSettings.enrichmentConcurrency` - User-configurable enrichment speed (1-5)
-   `SystemSettings.downloadSource` - Primary download source selection
-   `SystemSettings.primaryFailureFallback` - Fallback behavior on primary source failure
-   `SystemSettings.lidarrWebhookSecret` - Shared secret for Lidarr webhook signature verification
-   `User.tokenVersion` - Version number for JWT token invalidation on password change
-   `DownloadJob.targetMbid` - Index added for improved query performance

**Backfill Script (Optional):**

```bash
# Backfill originalYear for existing albums
cd backend
npx ts-node scripts/backfill-original-year.ts
```

### Breaking Changes

-   None - All changes are backward compatible

### Security

-   **Critical:** Bull Board admin dashboard now requires authenticated admin user
-   **Critical:** Lidarr webhooks verify signature/secret before processing requests
-   **Critical:** Encryption key validation on startup prevents insecure defaults
-   Session cookies use secure settings in production (httpOnly, sameSite=strict, secure)
-   Swagger API documentation requires authentication in production (unless `DOCS_PUBLIC=true`)
-   JWT tokens have proper expiration (24h access, 30d refresh) with refresh token support
-   Password changes invalidate all existing tokens via tokenVersion increment
-   Transaction-based download job creation prevents race conditions
-   Enrichment stop control no longer bypassed by worker state
-   Download queue webhook handlers use Serializable isolation transactions
-   Webhook race conditions protected with exponential backoff retry logic

## Release Notes

When deploying this update:

1. **Backup your database** before running migrations
2. **Set required environment variable** (if not already set):
    ```bash
    # Generate secure encryption key
    SETTINGS_ENCRYPTION_KEY=$(openssl rand -base64 32)
    ```
3. Run `npx prisma migrate deploy` in the backend directory
4. Optionally run the originalYear backfill script for era mix accuracy:
    ```bash
    cd backend
    npx ts-node scripts/backfill-original-year.ts
    ```
5. Clear Docker volumes for audio-analyzer if experiencing model issues:
    ```bash
    docker volume rm lidify_audio_analyzer_models 2>/dev/null || true
    docker compose build audio-analyzer --no-cache
    ```
6. Review Settings → Downloads for new multi-source download options
7. Review Settings → Cache for new enrichment speed control
8. Configure Lidarr webhook secret in Settings for webhook signature verification (recommended)
9. Review Settings → Security for JWT token settings

### Known Issues

-   Pre-existing TypeScript errors in spotifyImport.ts matchTrack method (unrelated to this release)
-   Simon & Garfunkel artist name may be truncated due to short second part (edge case, not blocking)
